iON+, ACCURE to streamline BESS data access
Author: Joe Peck
iON+, the data and asset performance management platform developed by Conrad Energy, has partnered with battery analytics provider ACCURE Battery Intelligence to simplify data access from battery energy storage system (BESS) assets.
Under the partnership, iON+ will provide data services to ACCURE customers through a data bridge that extracts and records high-frequency data from BESS systems.
The service will transfer data from BESS assets to the ACCURE platform in near real time. It can also return corrected values, including State of Energy (SoE), which can be used to inform dispatch and trading decisions.
Corrected battery data supports trading
The partnership is intended to reduce the time required to integrate BESS data, allowing iON+ to transfer high-frequency information from customers’ portfolios into ACCURE’s analytics platform.
ACCURE says correcting SoE can make additional energy available for trading and reduce penalties associated with overstating available energy.
The approach has been used at Gore Street Capital’s 75MW Dogfish BESS in Texas. ACCURE says analysis of operating data indicated an annual benefit of more than $110,000 (£80,655), equivalent to around a 5% increase against average BESS trading revenues in ERCOT. Corrected values went live at the site in July 2026 without additional hardware.
ACCURE’s platform monitors battery performance down to cell level, with the company’s engineers working with asset owners and operators to identify issues such as imbalance.
Rhys Kirk, Chief Technology Officer at iON+, says, “We are delighted to have formalised this mutually beneficial partnership with ACCURE. We have been working with ACCURE for some time and know from first-hand experience the breadth and quality of their analytics.”
Yannick Gindroz, Head of Partnerships at ACCURE, says, “The iON+ team’s experience in extracting and transferring high-granularity data made them an obvious partner for us. In our industry, visibility is everything, and so we are always looking for ways to show our customers more of what their assets are doing.”
